If you want a new AR-15 but are tired of shooting 5.56 and want something with a little more performance, the 6.8 SPC Type II cartridge was designed just for that. This Radical Firearms 6.8 SPC II AR-15 is a great option for hunting hogs and other game with the semi-automatic platform without the harsh recoil of larger calibers. This AR has a 16” barrel that is made from 4150 chrome moly vanadium steel and has a durable Melonite finish for long term wear resistance. The 1:11 twist rate of the barrel is optimal for the SPC Type II bullet and allows for better stabilization at higher velocities. A benefit of this caliber is that it packs more of a punch than standard 5.56 but uses mostly the same components, so you can easily upgrade your trigger, charging handle, or other lower parts. Not that you really need to because this Radical AR comes with an enhanced LPK that includes an ambidextrous safety and extended magazine and bolt release. All you need is your favorite optic and you are ready to hit the range.

Even better, this 6.8 AR-15 comes with a Mission First Tactical Minimalist stock as well as an MFT ergonomic pistol grip. In keeping with the light weight and ergonomic theme, it includes a Radical Firearms MHR free float handguard. This handguard is slim while still having plenty of options for customization. You can either use the forward mounted integrated picatinny rails or the M-LOK slots to attach your favorite lights, grips, or accessories at virtually any position. It also helps to improve airflow around the barrel allowing it to cool off faster and even helps with accuracy by removing pressure points on the barrel. Hunting medium sized game with the AR-15 platform has never been easier with the large variety of calibers to choose from and the 6.8 SPC Type II is one of the best.
